It depends on your prevailing philosophy - if you like the EAFP that
prevails in python, it's better to raise an error. Usually that indicates
that something has failed.
OTOH, a lot of people feel that using exceptions as control flow is bad
practice - they're exceptional so they should only arise in exceptional
case.
There may be performance issues, though I'm not familiar enough with that
yet.
just my two bits,
